That, however, is unlikely to send your ints in a way you expect. It is "casting" them to a different data type.

If you want to send those ints (16-bit signed numbers) as such, it would be better in your case to set up a loop, and in that loop do a Serial.print of each element, with something in-between (like a space, comma, newline, etc.).

Please post technical questions on the forum, not by personal message. Thanks!
